LTV 1200 Operator's Manual - CareFusion Emergency Preparedness

On/Standby
This button switches the LTV ® 1200 ventilator between Standby and On.
When the ventilator is on, the On/Standby LED will be on. The ventilator will operate on external
power if it is available, or internal battery, if there is no external power or the external power source is
depleted. The internal battery will be charged from the external power source while the ventilator is
operating on external power.
When the ventilator is in Standby, the On/Standby LED will be off, however, the internal battery will
continue to charge.
To turn the ventilator on from the Standby state:
1) Push the On/Standby button.
If the Patient Query feature is enabled/on when the ventilator is powered up, ventilation and alarm
activation are suspended and the message SAME PATIENT is displayed (see Presets in Chapter 10
- Extended Features).
• To enable the suspended alarms and begin ventilation with the settings in use during the last
power cycle, press the Select button while SAME PATIENT is displayed
OR
• To enable the suspended alarms and begin ventilation with Presets values appropriate for a
new patient, turn the Set Value knob until NEW PATIENT is displayed and press the Select
button. Then turn the Set Value knob until the desired patient type is displayed (INFANT,
PEDIATRIC or ADULT) and press the Select button (see LTV® 1200 Presets Table in
Chapter 10 – Extended Features for detailed settings information)
• Turning the Set Value knob until EXIT is displayed and pressing the Select button
returns the ventilator to the SAME PATIENT menu option/message
If no controls are activated for three (3) seconds while either the SAME PATIENT or NEW PATIENT
options are being displayed, an audible alert sounds. Activation of any control resets the 3 second
delay of the audile alert.
If the Patient Query feature is disabled/off when the ventilator is powered up and passes POST, it will
begin ventilation (appropriate alarms enabled) using the settings in use during the last power cycle.
To prevent autocycling, the Leak Compensation feature (if enabled/on) is suspended during the first
30 seconds of operation.
To prevent nuisance alarms, the LOW MIN VOL alarm (Low Minute Volume) is suspended for the
first 20 seconds and the HIGH f alarm (High Breath Rate) is suspended for the first 60 seconds of
operation.
To put the ventilator into Standby:
1) Push and hold the On/Standby button for 3 seconds.
2) An Inop alarm will occur. To cancel the Inop alarm, push the Silence Reset button.
• Verify a confirming audible chirp occurs after the alarm is silenced.
3) The Vent Inop LED will remain lit for a minimum of 5 minutes.
